Members of the management team at Okuma America Corporation are excited to announce the launch of a next-generation machining center to join the company’s horizontal machining center lineup. This new machine - the Okuma MA-600HIII – brings next-level machining capabilities to the MA-600H family by offering several new features.
Impressive 10K Spindle
The MA-600HIII’s new 10K RPM standard spindle effectively handles a wide range of applications, from heavy- duty to high-feed machining. The enhanced spindle is now equipped with a new thru-spindle coolant suction feature, which removes residual coolant inside the tool and spindle.
This next-generation horizontal machining center weighs in at a massive 55,000 pounds, ensuring structural stability and consistent precision machining operations for the long haul. This machine has a larger work envelope than its predecessor, with added X-axis travel capabilities. Additionally, the MA-600HIII can perform automatic tool change operations in less than four seconds flat! Additional enhancements have also been made to Okuma’s market-leading thermal management technology, including decreased temperature deviation of the machine to an improved 7μ (seven micron) dimensional change per 24-hour period. This is particularly effective when faced with severe swings in the ambient temperature.
Upgraded Chip & Coolant Management Systems
The Okuma MA-600HIII features an enhanced coolant management system, ball screw cooling for the X, Y and Z axes, an upgraded workspace design to prevent chip accumulation, and improved chip evacuation functionality. This level of innovation maximizes uptime and allows for long periods of continuous machine operation.
The all-new sludge-less tank technology activates sophisticated filtering and liquid flow patterns of the chip / coolant mixture to mitigate settling of the mixture in the bottom of the receiving tank. This new technology reduces the need for time-consuming tank cleaning and affords increased machine operation time.
The MA-600HIII's flexible design allows for a variety of automation applications. The workspace area can equip up to seven part loading/unloading ports or up to eight workholding clamp ports, which can help eliminate the need for complicated circuit arrangements for hydraulic applications. Up to 16 ports are available in the machine's setup station, expanding part capacity and the possibilities for robotic applications.

Related Glossary Terms
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- machining center
CNC machine tool capable of drilling, reaming, tapping, milling and boring. Normally comes with an automatic toolchanger. See automatic toolchanger.
- precision machining ( precision measurement)
precision machining ( precision measurement)
Machining and measuring to exacting standards. Four basic considerations are: dimensions, or geometrical characteristics such as lengths, angles and diameters of which the sizes are numerically specified; limits, or the maximum and minimum sizes permissible for a specified dimension; tolerances, or the total permissible variations in size; and allowances, or the prescribed differences in dimensions between mating parts.
- rapid traverse
Movement on a CNC mill or lathe that is from point to point at full speed but, usually, without linear interpolation.
- work envelope
Cube, sphere, cylinder or other physical space within which the cutting tool is capable of reaching.
